Patients with ankylosing spondylitis (AS) have an increased risk for cardiovascular mortality. The circulating ox-LDL/LDL ratio is associated with subclinical atherosclerosis in patients with systemic lupus erythematosus. In this study, we found that the ox-LDL/LDL ratio was increased in AS patients. The levels of serum RANKL and HMGB1 were also elevated in AS patients, and the number of CD68(+)/RANK(+) cells was increased in peripheral blood from AS patients. 0.03% ox-LDL in LDL, similar to the ox-LDL/LDL ratio in peripheral blood from AS patients, promoted cytoplasmic translocation and release of HMGB1 as well as RANK expression...

RATIONALE: Lymph node is a preferred site for extrapulmonary tuberculosis (TB). In the thorax, mediastinal tuberculous lymph nodes can erode adjacent structures such as heart, aorta, and esophagus, forming fistula, and causing fatal consequences. However, tuberculous bronchonodal fistula as a complication of lymph node TB in adults is rarely known in terms of imaging or clinical findings. Here, a case of isolated tuberculous bronchonodal fistula appearing as the first presentation of TB in a 74-year-old male with systemic lupus erythematosus (SLE) is reported...

Systemic autoimmune diseases (SAIDs) represent a group of syndromes involving at least two organ systems. Classical SAIDs include connective tissue diseases, vasculitis, and granulomatous diseases, many of which involve the nervous system and result in different neurological manifestations. Hydrocephalus can be a rare but lethal complication of various SAIDs, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), sarcoidosis, and primary vasculitis. However, the pathogenesis of SAIDs complicated with different types of hydrocephalus is varied and difficult to determine using the existing published data, and various manifestations and expressive forms of the conditions bring a substantial challenge to a timely clinical diagnosis and treatment...

Primary hemostasis begins with endothelial injury. VWF, produced by endothelial cells, binds to platelets and links them to subendothelial collagen. Platelet-derived ADP and thromboxane activate non-adhered platelets via their GPIIb/IIIa receptors, allowing these platelets to participate in platelet aggregation. Secondary hemostasis is initiated with the binding of factor VII to extravascular tissue factor (TF). Factors II, VII, IX and X are vitamin K-dependent factors. The role of vitamin K is to assist in the addition of gamma carboxylate groups to glutamic acids in the "GLA" domains of these factors...

Objective: Patients with SLE have increased morbidity and premature mortality. Whether this mortality gap has improved in recent years, as in RA, is unknown. Methods: We conducted a population-based cohort study using a medical records database representative of the general population of the UK. We identified incident SLE cases and matched non-SLE controls between 1999 and 2014, divided into two subgroups based on year of SLE diagnosis, forming the early cohort (1999-2006) and late cohort (2007-14)...

Background: Alopecia areata (AA) is a common, recurrent form of nonscarring alopecia which often presents as circumscribed patches of spontaneous hair loss. The global prevalence of this disease varies from 0.1% to 0.2% in general population and 7-30 cases per 1000 dermatological patients. The etiology of AA still remains uncertain; however, genetic or environmental factor and autoimmunity are claimed responsible for it. Various autoimmune diseases, such as Hashimoto's thyroiditis, diabetes mellitus, vitiligo, and lupus erythematosus, have been reported in association with AA...

Common DNA sequence variants rarely have a high-risk association with a common disease. When such associations do occur, evolutionary forces must be sought, such as in the association of apolipoprotein L1 (APOL1) gene risk variants with nondiabetic kidney diseases in populations of African ancestry. The variants originated in West Africa and provided pathogenic resistance in the heterozygous state that led to high allele frequencies owing to an adaptive evolutionary selective sweep. However, the homozygous state is disadvantageous and is associated with a markedly increased risk of a spectrum of kidney diseases encompassing hypertension-attributed kidney disease, focal segmental glomerulosclerosis, human immunodeficiency virus nephropathy, sickle cell nephropathy, and progressive lupus nephritis...

A recent clinical study showed that combination therapy consisting of mycophenolate mofetil, tacrolimus and steroids was shown to be more effective in achieving complete remission in patients with severe forms of lupus nephritis than conventional therapy consisting of intravenous cyclophosphamide and steroids. To explore the underlying molecular and cellular mechanisms of increased efficacy of the combination therapy regimen, we employed a mouse model of lupus nephritis, MRL/lpr mice, and treated them with monotherapies of prednisone, mycophenolate mofetil, or tacrolimus, or with their combination...

Monogenic lupus is rare, but its study has contributed immensely to a better understanding of the pathogenesis of systemic lupus erythematosus. The first forms identified were inherited complement deficiencies, which predisposed to lupus due to impaired tolerance, and aberrant clearance of apoptotic bodies and immune complexes. In recent years, several new monogenic disorders with a lupus-like phenotype have been described. These include forms that affect nucleic acid repair, degradation and sensing (TREX1, DNASE1L3), the type I interferon (IFN) pathway (SAMHD1, RNASEH2ABC, ADAR1, IFIH1, ISG15, ACP5, TMEM173) and B cell development checkpoints (PRKCD; RAG2)...

OBJECTIVE: The antiphospholipid syndrome (APS) is a systemic auto-immune disease with an unclear pathophysiology. The aim of our study was to understand the development of APS on a cellular level. Therefore, we analyzed the influence of human serum of APS patients on endothelial expression of specific genes and proteins in comparison to a control group. METHODS: In this study, we analyzed the expression of ICAM-1, VCAM-1, E-selectin and annexin V in primary cultures of human umbilical vein endothelial cells (HUVEC) in response to 10% (v/v) serum of control patients (n = 6), patients with systemic lupus erythematosus (SLE) and no APS (n = 4) or APS patients (n = 9) for 24 h...

Various kinds of immune cells -including dendritic cells, macrophages, T cells and B cells- express the vitamin D receptor and 1α-hydroxylase(CYP27B1). In vitro studies have shown the anti-inflammatory effect of 1,25-dihydroxyvitamin D:the active form of vitamin D. As vitamin D deficiency spread in our society, epidemiological studies have established the association between vitamin D deficiency and incidence or progression of several inflammatory diseases, including rheumatoid arthritis(RA), systemic lupus erythematosus(SLE), and multiple sclerosis(MS)...

Generally, the main complications of silicone implantation are local symptoms. However, some patients develop late-onset systemic symptoms often associated with a rare form of hyperactive immune response, as part of a syndrome known as autoimmune syndrome induced by adjuvants (ASIA). Reported cases of ASIA have shown resolution with explantation, but not with immunomodulatory therapy. In this report, we described a case of a previously healthy 23-year-old woman, who has undergone silicone breast implant augmentation, for aesthetic reasons, and developed localized cutaneous impairment 3 years postsurgery...

A middle-aged man with decompensated cirrhosis and a dimorphic multisite skin rash is diagnosed with rare atypical herpes simplex infection, manifesting Sweet's syndrome (SS) in the absence of other described associations. SS, an acute febrile neutrophilic dermatosis, has three common forms-classical or idiopathic, malignancy associated and drug induced. Systemic autoimmune, connective tissue diseases and infections are also strong associations. The latter is commonly described in Gram-positive bacteria, salmonellosis and Yersinia Herpes infections are a rare cause of SS, reported only thrice in literature, one with concomitant lupus, the second with associated mycobacterial infection and third, in metastatic breast disease in contrast to our patient...

Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease characterized by auto-antibodies against native deoxyribonucleic acid after modification and is one of the reasons for the development of SLE. Here, we have evaluated the structural perturbations in human placental DNA by peroxynitrite using spectroscopy, thermal denaturation and high-performance liquid chromatography (HPLC). Peroxynitrite is a powerful potent bi-functional oxidative/nitrative agent that is produced both endogenously and exogenously...
